SHANK CREASING, COLORING, AND STAMPlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 224,030, dated February 3, 1880.

Application filed December 13, 1879.

To all whom it may concern:

Be it known that we, ARTHUR W. MUssELLs and JOHN PRAY, both of Lynn, in the county of Essex and State of Massachusetts, have jointly invented a new and useful Shank Channeling, Coloring, and' Stamping Machine, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of our invention is to accomplish in an expeditious and uniform manner, by the aid of machinery, the cuttingor creasing of the tread-surfaceof a boot or shoe shank,and

coloring the outer portions of said shank, bounded by said cuts or creases, which has up to the present time, at least so far as we are aware, been done by hand requiring skilled workmen to do the work, and even then it was a slow and consequently expensive job.

Our invention consists in certain mechanical devices for accomplishing this end, and combining therewith devices for stamping upon one or more soles the monogram or trademark of the manufacturer and the size-number of the boot or shoe at the same time that one or more shanks are being creased and colored, all of which will be best understood by reference to the description of the drawings, to be hereinafter given, in which- Figure 1 is a front elevation of a machine embodying our invention. Fig. 2 is an end elevation. Fig. 3 is a vertical section on line a: m on Fig. 1. Fig. 4. is an inverted plan of a shaft D, connected by the toggle-links E and the combined action of said springs and the nuts a and a.

L is a table or plate mounted upon and adapted to be revolved about the rod A, and to bemoved up and down thereon by combined action of the force of gravity and the upward movement of the bed F, upon which it rests.

Upon the upper side of the table or plate L are mounted four lasts or shoe-supports, M, two at each end, the toes of the pair of lasts at the left hand pointing toward the rear, and the toes of the pair of lasts at the right pointing toward the front, as shown. These lasts 0r shoe-supports M are attached to the table or plate L by means of the pins 1) and b in such a manner that they may be readily removed and others of different shape or size substituted therefor.

To the under side of the cross-head J, between the rods A and A, are secured two dies or stamps, NN, upon the lower faces of which are cut the monogram, trademark, or other designating character of the manufacturer, said dies being fitted to dovetailed grooves in the under side of said cross-head, and in such a position thereon that they will act upon and stamp the character engraved or cut thereon upon the soles of two shoes placed one upon each of the two lasts at the right-hand end of the table or plate L.

O O are two stamps having cut on their lower ends numbers to designate the size of the shoe, said stamps being adj ustably secured to the cross-head J, directly in the rear of the dies N N, as shown in Fig. 3.

At the left of the rod A are secured to the under side of the cross-head J, directly over the two lasts at the left-hand end of the table or plate L, the devices for channeling or creasing and coloring the desired portions of the shoe-shanks, consist-ing of one or more curved knives or creasingdies, one or more colorfountains, one or more pads of sponge or other absorbent material, and means of moving said pads up and down, as follows: 7

P P are stands secured to the cross-head J by means of screws 0 0, which pass through slotsin said stands and screw into the crosshead in such a manner that said stands may be adjusted in a horizontal plane, so as to bring their front ends nearer together and their rear ends farther apart, or vice versa,

the pendent portions of said stands being curved horizontally and placed in pairs with their convex sides toward each other, as shown in Fig. 4C.

To the concave side of each of the stands 1? P is secured the knife cl, fitted to said concave surface of the stand 1?, and provided with the short return or angular portion (1, the lower edge of said knife being curved to fit the curve of the shoe-shank, and projecting below the under surface of the stand P a distanceequal to the depth that it is desired to cut into the sole.

6 is a color-fountain provided with a wiregauze or perforated bottom, 0, a socket beneath said perforated bottom to receive a pad of sponge or other suitable absorbent material, f, and a feed-aperture, g. The fountain c is suspended from the rod h of the hinged operatin g -frame R by means of the eyebolt e, screwed into the top of said fountain, as shown in Fig. 5, and is guided in its up and down movements by the lugs' j, projecting from opposite ends thereof, and the guide-wires 70 it, set in the flange of the stand P, as shown.

The frame R is provided with the handle R, by which it maybe vibrated about its hingepivot l, to raise or depress the inking or coloring pad f at will.

The rods h h are fitted to slots in the front and rear bars of the frame R in such a manner that they may be adjusted toward or from each other as the two knives of a pair are adjusted toward or from each other, to adapt them to the width of the shank of the particular style of shoe being operated upon.

Although we have shown four lasts or shoe-.

I supports attached two at either end of the swiveling table L, it is obvious that a greater or less number of lasts may be used without aflecting the principles of operation, which are substantially as follows: Boots or shoes bein g placed upon all of the lasts, by moving the table L around its axis of motion till said lasts are removed from beneath the cross-head, the table L is rotated into a position which shall bring the shank portions of the shoes on one pair of lasts beneath the knives d d and the shanks of the shoes upon the other pair of lasts beneath the dies N and stamps 0, when the operator places his foot upon the treadle I, and, depressing it, raises the bed F and table L, and presses the soles of the shoes hard against the knives d d and dies or stamps N and 0. He then places his hand on the handle R and depresses the frame R, whereby the padsf are brought into contact with the soles of said shoes and deposit upon the portions of said soles which are outside of said knives coloring-matter. By this operation the shoes upon the lasts at the left-hand end of the table L have their shanks creased and colored, while the shoes at the right-hand end of said table have stamped thereon a number and a monogram or other designating-mark, when, having raised. the frame It and removed his foot from the treadle, the operator reverses those that were previously creased and colored, when the shoes are removed and others placed on the lasts, and the operations are repeated or the operator may place shoes upon the lasts at one end only of the table L in the first instance, move the table aboutits axis till said shoes are in proper position beneath the knives d d, raise said table to crease and color their shanks, move the table through one-quarter of a revolution about its axis to bring the unoccupied lasts in front of the ma chine, place shoes thereon, move said table another quarter of a revolution to bring the last-mentioned shoes under the knives d d and those previously creased and colored under the dies and stamps N and O, raise the table L to channel and color the shoes at one end of the table and stamp those at the other 'end thereof, then move said table one-quarter of a revolution about-its axis to bring the shoes which have been creased, colored, and stamped in front of the machine, remove said shoes and place fresh ones upon the lasts, rotate the table another quarter of a revolution in the same direction to place said fresh shoes beneath the knives d d, continuing the operation by applying shoes to one end of the table between each two movements of the treadle.

To enable shanks of shoes of the same general style, but having slightly-different horizontal curves to their shanks, to be creased by the same knives, we cover the shanks of the lasts with rubber or other suitable elastic material, m, which, by its elasticity, allows the sole to accommodate itself to slight differences between the horizontal curvatures of the lower edges of the knives and the shoeshanks.

WVhat we claim as new, and desire to secure by Letters Patent of the United States, is

1. An organized machine for cutting or creasing and coloring the shanks of boot or shoe soles, embodying the following elements, viz: one or more knives of an outline and shape adapted to cut or crease the inner .outline of the portion of the shank to be colored by direct pressure, a last or shoe-support mechanism adapted to cause said last and knife or knives to approach each other, and an absorbent color-pad adapted to be brought in cond, color-fountain e, having secured thereto the absorbent pad f, and attached to and adapted to move with and upon said stand P, and a pivoted operating-lever adaptedto impart to said fountain and pad a reciprocating motion, substantially as and for the purposes described.

4. In an organized machine, the combination of a pivoted table adapted to be rotated about a vertical axis passing through the center of its length and having one or more lasts or shoe-supports mounted upon each end thereof, a cross-head placed above said table, one

or more knives, d, and one or more color-foun-' tains, e, and absorbent-pads f, mounted upon the under side of said cross-head above the I ble stands, P, each having secured thereon a shank-creasing knife, d, two or more colorfountains, 0, each having an absorbent pad at tached thereto, and each mounted upon and movable with one of said stands P, and the pivoted frame-lever B R, provided with the rods h It, all arranged and adapted to operate substantially as and for the purposes described.

6. The combination of two or more adjustable stands, 1?, each provided with ashankcreasing knife, (1, and having attached thereto and adapted to be moved thereon and therewith a color-fountain, and an absorbent pad, and the pivoted jframe-lever R R, provided withtwo or more adjustable rods, h h, all arranged and adapted to operate substantially as and for the purposes described.

Executed at Lynn, Massachusetts, this 9th day of December, A. D. 1879.
